I ran some tests tonight with my program that uses Ken Silver's system to play Texas Cash Five (a 5/37 game). I won the 4/5 twice in the last two weeks. By my standards, that is pretty good. I have only won 4/5 four times in the last two years. My main problem with Cash Five is that the grand prize is at most $25,000. What always draws me back to Cash Five is that you can win $2 for a 2/5 win that costs $1.
